That's exactly the right f(x,y). Because you've got a rectangular prism, the upper surface that you're trying to integrate in the double integral case is just a constant flat plane, 5 units above the xy plane. So to use double integrals, you'd have to integrate f(x,y) = 5 between x in [0, 2] and y in [0, 3].
